CORVID.^'. 
Ohs . — The pied variety of the Eaven which so frequently 
occurs ill Faroe lias not as yet, so far as I know, been observed 
in Shetland. I have examined many specimens of these pied 
Eavens, but in each of them the markings have been unsym- 
metrical. The idea formerly entertained that it was a distinct 
species is now, it appears, entirely abandoned. 
THE CAEEIOX CEOW. 
Corvus corone. 
Earely seen, and only after severe gales. I have never

ants with the Eook, a more frequent visitor. 
THE HOODED CEOW.

CRAA — HOODIE CRAA. 
Closely resembling the Eaven in most of its habits, the 
Hooded Crow fully makes up by its boldness and perseverance 
for such advantage as the other may possess in point of bulk 
and strength. Its great abundance also tends, in no small degTee, 
to render it a very formidable “ pest of the farm.” It is, gene- 
rally speaking, bolder than the Eaven, but it less frequently

tremities by hunger, or by the necessities of a clamorous brood, 
it will kill young lambs, and fearlessly attack domestic ducks 
and fowls I am quite convinced that it pairs for life; and 
the idea is strengthened by the fact that when a flock is 
thoroughly dispersed, by means of a gun or otherwise, couples 
of old birds fly off together. The large flocks which assemble 
in spring have given rise to the extraordinary accounts one occa-
